Technibelt developed belt cleaning system performance specifications for a number of new coal handling and preparation plants in NSW and QLD. The average preset performance guaranteed carry-back level across all run-of-mine, reject and product conveyors was 10-12 kg/hr. The design and commissioning of Technibelt custom belt cleaning systems resulted in an average carry-back level of <1 kg/h with an average over the first 5 years of <5 kg/hr. Belt scraper adjustments and maintenance are based on actual performance (carry-back test data) not time in service. Belt cleaning system performance and scraper/conveyor component life continue to exceed operational, maintenance and life cycle cost expectations of our client.
